You're probably right... :-/
BTW, (pardon my ignorance) what is the most portable way to
do the equivalent of a os.system("cmd &") as native OS
API call ? [On Unix, "cmd &" starts a new process which runs
in the background and detached from the calling process.]
I've looked at .execve and .spawnve, but they both replace
the current process.
